The State Banking Commissioner shall act upon and issue an order granting or denying each application for a certificate of authority. If the Commissioner finds that the application should be granted, the Commissioner shall designate the amount of deposit accounts required and fix a reasonable time within which the funds subscribed may be placed in escrow in a bank or trust company approved by the Commissioner, to be delivered to the association after incorporation or returned to the subscribers if incorporation is not completed. The Commissioner may also require the incorporators to advance funds necessary to pay organizational expenses and other expenses for starting business, such advances to be repaid by the association after its incorporation and the granting of its certificate of authority, in the case of a stock association, or after its income is sufficient to meet reserve requirements, in the case of a mutual association, and further, in the case of a mutual association, to pay reasonable earnings on the deposit accounts of the association. If and when all requirements are met, a certificate of authority shall be issued by the Commissioner. The Secretary of State shall file the approved certificate of incorporation upon receipt of the incorporation fee. If the deposit accounts of the association are to be insured, approval shall be contingent upon the making, by the proposed association, of a bona fide application for insurance of accounts and deposits by the Federal Deposit Insurance Corporation and upon approval of such application by the Federal Deposit Insurance Corporation.
